When I was in the Philippines, we all kept a couple praying mantises inside our sleeping net to catch any mosquitoes that might get in during the day.

The seventeen year locusts (cicadas) in New England never were any problem except that the female buried her eggs about a foot from tip of branches, which would die and droop, a minor cosmetic blemish. I rembember them very well because my tinnitus causes illusion quite reminscent of them.
